Tamper-Resistant Nightlight With Locking Element And Dimming Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nightlights lack tamper-resistance, allowing children to easily remove them, which can lead to safety risks and loss of the device, and they often do not offer adjustable lighting options.
Innovation Solution
A dimmable tamper-resistant nightlight design featuring a body with plug blades that electrically couple to an electrical receptacle, a dimming switch for adjustable luminosity, and a locking element that prevents removal by positioning behind an electrical wall plate, ensuring the nightlight remains securely plugged in.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking element is added to prevent removal, then tamper-resistance is improved, but device complexity increases
Solution Approach 1:
The locking element is nested within the housing structure, utilizing the existing spatial framework of the nightlight device. The locking element engages with the electrical wall plate through a mechanism that is integrated into the housing, rather than being a separate external component, thus adding security functionality while minimizing increase in overall device complexity.
2Adaptability or versatility
If a dimming switch is added for adjustable luminosity, then adaptability is improved, but device complexity increases
Solution Approach 1:
The dimming switch is integrated into the existing housing structure, allowing a single component to serve multiple functions: it provides luminosity adjustment while being incorporated into the overall device assembly. This multi-functional approach enhances adaptability without proportionally increasing device complexity, as the switch shares structural space with other components.
3Reliability
If the locking element is positioned behind the wall plate, then tamper-resistance is improved, but ease of operation deteriorates
Solution Approach 1:
The locking element is strategically positioned at a specific location behind the electrical wall plate, creating a localized security feature. This positioning allows the locking mechanism to engage with the wall plate structure at a point that is not easily accessible to children, providing tamper-resistance while maintaining ease of operation for authorized adults who can access the backside of the wall plate for installation and removal.

Implementation Method 1
a body with at least one light emitting diode (LED)
Data Source
AI summary
A dimmable tamper resistant nightlight may include a body comprising at least one light emitting diode (LED). Plug blades may extend from the body. A dimming switch may be coupled to the at last one LED, the dimming switch configured to move between a first position that activates about 50% luminosity of the at least one LED, a second position that deactivates about 100% luminosity of the at least one LED, and a third position that activates about 100% luminosity of the at least one LED. A housing may be coupled to the body, the housing comprising an access opening through which the dimming switch may be moved among the first position, the second position, and the third position. A housing may also comprise a locking element configured to prevent the dimmable tamper resistant nightlight from being removed from the electrical receptacle.
